Abstract
Description
Die Erfindung betrifft ein netzbetriebenes, vorzugsweise aus dem öffentlichen Wechselspannungsversorgungsnetz betriebenes, elektrisches Gerät, wie bspw. und insbesondere ein Vorschaltgerät für Leuchtmittel, wie Gasentladungslampe(n) oder LEDs. Insbesondere bezieht sich die Erfindung auf ein solches Vorschaltgerät mit verbesserter elektromagnetischer Verträglichkeit (EMV). The invention relates to a mains operated, preferably operated from the public AC power supply, electrical device, such as, and in particular a ballast for lighting, such as gas discharge lamp (s) or LEDs. In particular, the invention relates to such a ballast with improved electromagnetic compatibility (EMC).
Es ist bekannt, dass elektronische Vorschaltgeräte und auch andere netzbetriebene Geräte elektromagnetische hochfrequente Abstrahlungen erzeugen, die als Störungen in Erscheinung treten und ein bestimmtes Maß nicht übersteigen sollen. Die von dem Gerät ausgehenden Störungen können sowohl durch direkte Abstrahlung wie auch über Zuleitungen verbreitet werden. Zuleitungen können dabei als abstrahlende Antennen wirken. It is known that electronic ballasts and other mains operated devices generate electromagnetic high frequency emissions that appear as disturbances and should not exceed a certain level. The interference emanating from the device can be spread both by direct radiation as well as via cables. Supply lines can act as radiating antennas.
Zur Minderung solcher elektromagnetischen Störungen schlägt bspw. die
Bei dieser Lösung ist keine direkte galvanische Verbindung zwischen dem Masseanschluss des Geräts und dem Schutzleiter vorhanden, was gelegentlich abgelehnt wird.In this solution, there is no direct electrical connection between the ground terminal of the device and the protective conductor, which is occasionally rejected.
Weiter ist aus der
Auch stellt sich zunehmend die Forderung zur Beschränkung der Störabstrahlung im höherfrequenten Bereich, bspw. im Frequenzbereich von 50 MHz bis 300 MHz, insbesondere bei 100 MHz. Derartige Störabstrahlungen verhalten sich anders als weniger hochfrequente Störungen.Also, there is an increasing demand for limiting the noise emission in the higher-frequency range, for example in the frequency range from 50 MHz to 300 MHz, in particular at 100 MHz. Such noise emissions behave differently than less high-frequency interference.
Es ist Aufgabe der Erfindung, ein netzbetriebenes Gerät bereitzustellen, das einerseits den entsprechenden Anforderungen für elektrische Sicherheit genügt und andererseits eine geringe Störabstrahlung, insbesondere eine geringe hochfrequente Störabstrahlung aufweist. It is an object of the invention to provide a mains-powered device, on the one hand satisfies the corresponding requirements for electrical safety and on the other hand has a low noise emission, in particular a low high-frequency interference emission.
Diese Aufgabe wird mit dem Gerät nach Anspruch 1 gelöst:
Bei dem erfindungsgemäßen Gerät ist zwischen dem PE-Anschluss einer Netzklemme und einer netzspannungsführenden Leitung ein Zweig vorgesehen, in dem eine Reihenschaltung, bestehend aus einem Y-Kondensator und einer Resonanzbaugruppe, vorgesehen ist. Die Resonanzbaugruppe ist vorzugsweise darauf ausgelegt, den Durchgang von hochfrequenten Störfrequenzen zu behindern. Sie verhindert damit, dass hochfrequente Spannungen über den PE-Anschluss auf den Schutzleiter gelangen, der dann als Antenne wirken und diese hochfrequenten Spannungen abstrahlen könnte.This object is achieved with the device according to claim 1:
In the device according to the invention, a branch is provided between the PE terminal of a network terminal and a mains voltage-carrying line, in which a series circuit consisting of a Y-capacitor and a resonant assembly is provided. The resonant assembly is preferably designed to hinder the passage of high frequency noise. It thus prevents high-frequency voltages from reaching the protective conductor via the PE connection, which then acts as an antenna and could radiate these high-frequency voltages.
Andererseits werden weniger hochfrequente Störspannungen weniger stark behindert und somit über den PE-Anschluss auf den Schutzleiter gegeben. Dieser ist jedoch für die weniger hochfrequenten Störungen niederohmig und schließt diese ohne schädliche Abstrahlung kurz. On the other hand, less high-frequency interference voltages are less impeded and thus given over the PE connection to the protective conductor. However, this is low resistance for the less high-frequency interference and closes this without harmful radiation short.
Vorzugsweise weist die Resonanzbeaugruppe mindestens eine induktive Komponente und eine kapazitive Komponente auf. Außerdem kann eine dissipative Komponente vorgesehen sein. Die induktive Komponente und die kapazitive Komponente sind vorzugsweise so aufeinander abgestimmt, dass sie eine Parallelresonanz, d.h. ein Impedanzmaximum, definieren, das vorzugsweise zwischen 50 MHz und 200 MHz, vorzugsweise bei 100 MHz liegt. Die Güte des von der induktiven Komponenten und der kapazitiven Komponente gebildeten Parallelresonanzschwingkreises ist vorzugsweise wenigstens so hoch, dass die in der Resonanz allein wirksame dissipative Komponente einen Wert zwischen 1 und 3 kΩ, vorzugsweise 2 kΩ aufweist.Preferably, the resonant assembly has at least one inductive component and one capacitive component. In addition, a dissipative component may be provided. The inductive component and the capacitive component are preferably matched to each other to produce a parallel resonance, i. an impedance maximum, which is preferably between 50 MHz and 200 MHz, preferably at 100 MHz. The quality of the parallel resonance resonant circuit formed by the inductive component and the capacitive component is preferably at least high enough for the dissipative component acting alone in the resonance to have a value between 1 and 3 kΩ, preferably 2 kΩ.
Während die induktive Komponente vorzugsweise einen Wert zwischen 5 µH und 10 µH aufweist, hat die kapazitive Komponente vorzugsweise einen Wert zwischen 0,1 pF und 1 pF, vorzugsweise 0,4 pF. While the inductive component preferably has a value between 5 μH and 10 μH, the capacitive component preferably has a value between 0.1 pF and 1 pF, preferably 0.4 pF.
Der Y-Kondensator weist vorzugsweise eine Größe auf, die im Wesentlichen dem 10000fachen der kapazitiven Komponente der Resonanzbaugruppe entspricht. Vorzugsweise liegt die Kapazität des Y-Kondensators zwischen 1 nF und 4,7 nF, vorzugsweise beträgt sie zwischen 2,2 nF und 3,3 nF. Auf diese Weise kann durch die Wechselwirkung zwischen der Resonanzbaugruppe und dem Y-Kondensator eine Serienresonanz (Impedanzminimum) erbracht werden, die ungefähr bei einem Hunderstel der gesperrten Frequenz, z.B. bei etwa 1 MHz liegt. Somit werden niederfrequente Störanteile (um 1MHz) wirksam kurzgeschlossen.The Y capacitor preferably has a size substantially equal to 10,000 times the capacitive component of the resonant assembly. Preferably, the capacitance of the Y capacitor is between 1 nF and 4.7 nF, preferably between 2.2 nF and 3.3 nF. In this way, by the interaction between the resonant assembly and the Y-capacitor, a series resonance (impedance minimum) can be provided, which is about one hundredth of the locked frequency, eg at about 1 MHz. Thus, low-frequency interference components (around 1 MHz) are effectively short-circuited.
